X6 connection problems and ovi problems
My new X6 won't connect to the ovi software through my computer, it connects but then says errors and i cant sync it wih the computer or check my messages for things i need to save.
i also cant use the phone as a modem as it says its not found although it is..
i;ve tried reinstalling ovi but no success, previous ovi worked fine with the nokia 5800 and it didnt with the x6, so i changed it and updated online to no avail.
Its unlikely the first line support would know what to tell Openreach, as it usually a process that takes place with "repeat faults".
It can be due to corroded "crimp" joints, where its not possible to open the connection up. Usually the joint is simply replaced with more modern crimp connectors, that do not normally suffer from corrosion. Its a very quick thing to do.
If you do have any difficulty then
If you would like to contact one of the UK based BT Care Team who moderate this forum, they should be able to ask Openreach to do it.
They can be contacted using this link BT Care Team
They normally respond by phone or e-mail, within three working days, however you should get an immediate confirmation, with a tracking number.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

X6 and ovi suite sync problem - usb connection
i recently bought an x6 and set up ovi suite etc which all worked fine! yesterday i updated maps and the x6 operating system using ovi which again seemed to work fine. Now however when i connect phone to my pc the pc comes up problem with hardware installation and ovi suite only occassionally recognises phone - even when it does it will not sync music! help please - wish i hadn't updated anything as it all worked fine before !!!!
I have a similarly frustrating sync problem with my X6. It's my second phone too.
I've had Ovi Suite installed on my computer for about 9 months. I had difficulty getting it to sync with my X6 phone at first but after some troubleshooting I got it working reasonably well.
However over the last few months it doesn't initiate the syncing process after I connect my device. I can open Ovi Suite and click the sync buttons but it doesn't do anything.It doesn't freeze or crash either which is strange considering it is not processing the request.
I've tried everything including reinstalling the software and resetting my phone. This worked once and since went back to it's old tricks.
The only thing that works is removing the X6 device in OVI suite, rebooting the PC and adding the device again. This is real pain in the backside as you can imagine doing this each time I want to sync it.
In contrast the previous version - PC Suite - worked well with my old Nokia phone.
Nokia support have provided some guidance after pushing for a reply but you dont get expert or timely help from them.
Come on, we cant be just a few people having these issues? I reckon lots of x6 owners aren't getting full value from these devices.
It's at the stage where I'd not recommend a Nokia x6 or other Nokia phone to anyone wanting the PC connectivity which is one of the major benefits of a phone these days.
Go on Nokia give us some love!

Outlook Express and Ovi Suite syncing problems
Hi,
I just installed the Ovi Suite for my new N5230 phone.
I tested syncing contacts for the first time from Outlook Express to the phone and my account at Ovi.com via Ovi Suite. All went fine.
However, I undertook a major edit of all my Outlook Express contacts data (thankfully backing it up afterwards on my PC) but when I went to use the sync fucntion in Ovi Suite again I was not given an option of (a) whether to merge or replace or (b) where to start sync from if not a merge. Consequently my phone and Ovi.com contacts lists filled up with duplicates through a botched merge. Where a contact was deleted in Outlook Express no Sync Conflict message appeared to ask me if I wanted to delete the same entry in Ovi.
When I deleted all the contacts in Ovi Suite and tried to sync again my Outlook Express contacts list was deleted! Thankful for the backup before I started this waste of a Sunday afternoon.
So basically, is it the case that if I want to use Ovi Suite and Ovi.com for contacts then I have to use Ovi.com as the master list and not my contacts list in Outlook Express on my PC? If the software simply merges data all the time how the heck am I meant to delete a contact from all three storage areas?
Any advice appreciated.
BillWell for anyones information. Syncing with ovi suite.
I have successfully got ovi suite working.
For those with problems this is what I did. I have vista.
1. I uninstalled all programs from nokia.( ovi suite using the online uninstaller. Pc suite using the installed uninstall program.
then i ran pc suite cleaner.
2. using search for nokia then using advanced search for all nokia folders remaining (important to use advanced search or you will miss some of the folders and files. Then deleted them. Some you may have to change the user permissions to delete them. It is important to delete these as they hold data and i think might be one of the conflicts stopping sync working.
3. Delete any remaining files except bookmarks pics etc.
now there should be nothing on the pc.
Then download and run ccleaner. Cleaner and registry.
Reboot pc
Then download ovi suite.
A wizard might pop up but if not start ovi suite and connect your phone. I turned bluetooth off and used usb.
The phone will download settings. You can select pc suite on the sync settings in the phone. not ovi.com.
the program is good and worth the trouble. It saves your messages and contacts as well as syncing contacts and calendar with your required program, also bookmarks can be saved with firefox and explorer in your phone folder in favourites. It creates the folder. To transfer bookmarks from pc to phone ensure they are in this folder.
This took me a lot of reboots and time with a few calls to nokia and i am still waiting for their callback!!!
It also works fine on my xp computer too. -
5230 connection problems on Software update and Ov...
Hi,
I recently bought a 5230 on a talk mobile monthly contract and I'v had a few connection problems. First of all I can't check for updates for my phone or the software on it. I just get an error message which says 'connection error'.
Similarly with Maps it simply won't connect to the internet saying 'something went wrong with the connection, please try again'.
The other internet accessing functions of the phone, like the browser and ovi store etc, work fine. Does anybody have any ideas as to what the problem might be?I am on Pay & Go with o2 which includes web - same old prob with accessing ovi maps - will not allow connection to the internet - in spite of apparently managing to update the latest software - as o2 suggested. Don't know what to do or where to go next for help. Nokia support - zero - wish to hell I had never bought the phone as it has caused me no end of grief - time for an iPhone methinks!

N97 - Ovi Suite Connection Problem - Windows 7
Hi all.
I have N97, firmware version 20.0.019 (t mobile - **bleep** with the old firmware updates.... )
I am running windoze 7 with all updates etc.
I have the latest version of nokia Ovi Suite and the latest version of Nokia PC Suite.
I am reluctantly trying to get used to using ovi suite instead of PC ever since Nokia's update page seemed to suggest I should be using OVi suite with this phone.
Anyway bluetooth connection is working fine. I can do all syncs with everything on bluetooth.
USB connection is not, when the phone is connected, and I select PC Suite on the phone, the phone and PC then get stuck in a sort of loop where the PC is "installing drivers" and the phone keeps asking me to select PC Suite mode. Occasionally I get an error message saying I am stuck in file transfer mode.
I have also tried this after going into settings and setting USB connection mode to PC SUITE only, with Don't Ask selected.
This is profoundly frustrating and also renders the ability to update phone software totally useless because you cannot update via bluetooth, only USB connection.
I am getting mighty peeved off with Nokia's ability to get firmware, and software products right. Come on guys, hire some decent developers, and/or start responding to feedback from customers like me. (I'd happily beta test any software, I've done it before for an online game......!!!!)
I am considering selling my N97 online, and just buying an unlocked HTC HD2 after over a decade of using Nokia phones.
help!
RAmazing that so many have responded to this post, and not one has come close to the right answer... I've had the same problem for a while, and at first I thought it was just my old XP notebook - which had more than one problem - or the general poor performance we've come to expect from the N97. I couldn't even sync on Ovi. But with my new Windows 7 notebook in hand, I was all excited to finally update the firmware on my phone - which had been stuck on v12 for a while. Imagine my surprise when I still had the same problems with my brand-new notebook. I started browsing around for more help than this thread, and found that Nokia has released a software update program seperate from Ovi Suite. Just google "Nokia Software Updater for Windows 7" or whatever version of windows you have, download & install. You might need to kill three "Nokia..." processes in the Task Manager to let it run, because it seems Ovi suite has these processes starting up with Windows. (Amazing when they program applications to do that without your permission!) Why on earth would Ovi Suite need to run three processes on my machine anyway, if I haven't even started up the program after reboot? But still, this program wouldn't connect to my N97 via USB. I clicked on the icon in the system tray showing the drivers installing after I plugged it in, and found the culprit: The installation of the driver for "MTP USB Device" failed. Googled that, and found that there are a lot of people having problems with that, from cameras to cellphones to mp3 players. Tried a few suggestions I found, and ended up having to uninstall all my (brand new?) USB controllers (under "Device Manager") and deactivate Windows Media Player from "Windows Features", reboot, then re-activate Windows Media Player - something to do with MTP Devices getting their drivers from Windows Media Player. Not sure if it was one or both of these fixes, but then Nokia Software Updater connected to my N97 with no problem. Installed the software update, and now all is good again. Incidentally, after the software update was complete, a whole bunch of different drivers were installed when I connected the USB... the main one changed from "Nokia ... Parent ..." something to "Nokia... Flashing..." something - and Ovi Suite connects fine now as well! Good luck to everyone who had this problem - it's been fun.

Nokia X6 connection problem with ovi suite
I had recenly bought a nokia x6 16gb and I have connection problem with my ovie suite.I am using cable to connect to the pc.When I open my ovie store it says connect ur device under the ovie suit toolbar. And I connect it but it actually worked but it work for about 5sec and it auto dissconnected.I had tried reconnecting it but turn out the same.But when I am using my laptop and I connect it using Bluetooth it work (ONLY FOR TRANSFER SONG AND PHOTO).I cant update my phone software because I am using bluetooth.I also tried using cable to my laptop but it is same like how I connected to my pc.I am using Windows XP SP2(PC).Thank you for those who helped me and spending time reading it.(Reason=Because I wanna update my phone Software).Again Tks
Hi PhoneNerdies,
Firstly, I recommend to update your Windows XP to Service pack 3. Nokia Ovi Suite do not support fully the XP with service pack 2.
Then use the latest Ovi Suite available, current version is 2.2.0.245 and available from Nokia.com and Ovi.com download pages. You Ovi Suite version you find from help menu and About the Ovi Suite tag.
Then update your X6 to the latest SW available.
After these steps your X6 would work fine.

Timeouts and connection problems after 5.1(2) upgrade
AIM/chat and some other programs are having timeout/connection problems after upgrade to 5.1(2). I am using S241 also. The connection problems stopped when the IPS was set to bypass. Rebuilt IPS and left sigs at default settings and problem is still happening. I am not seeing any of the IPs that are having the problem in the Event Viewer or on the Events in the IDM.
Any known issues with the 5.1(2) that would cause this type of problem?I don't know specifically, but I did notice that 5.1(3) was released today.

Unending connectivity problems -- and Desktop Help...
I'm wasting so much time on connectivity problems that it's positively wearying. Prior to the installation of BT Infinity here in April, I had a low quality broadband service because of the length of the line from the exchange: if I could get a download speed of 1.2Mbps and an upload of a quarter of that, I was doing well.
BT advised that thanks to fibre optic, my Internet should run much faster. So we had Infinity installed. I'm registered with Speedtest.net so am able to see my performance record.
The average download speed is now aroun d 6Mbps and the average upload, more than that at 7Mbps. How an upload speed can consistently be faster than a download escapes me.
But I'm not familiar with the ways of Internet connectivity and try as a I might, can't get my head around it.
This desktop computer runs Vista OS. Vista was **bleep** when it came out and is renowned for its botched handling of Internet connections. So I'm not blaming BT for the literally unending connectivity problems that are occurring now, with line drops, speeds slowing to a crawl, and no guarantee that any connection will last. But it would be good to actually use BT software to help fathom out what's going wrong here, and today's typical morning which looks like this:
1) Boot up computer. Automatic connection to hub via Netgear USB wireless adapter. Hub is on ground floor of this 3-storey property but signal strength from hub is excellent, as confirmed by inSSIDer monitoring, currently showing 54 with no other networks anywhere near that figure.
2) Perhaps 5 minutes after connection established, it's then lost. 'Local Only' is displayed. This is, apparently, a known Vista problem. But Microsoft has issued a fix for it. I know this, because it took 100 hours of ploughin g the Net to find out that MS had finally admitted to one more Vista screw-up. I've used the Microsoft router "fix it" before and it didn't work ("failed to process") so uninstalled it and have DL'd it again now and run it. This time it says it has fixed everything.
3) Computer is re-booted to make the fix effective. Computer connects to Internet. Speedtest.net check yet again confirms that upload speed is faster than download speed.
4) Connection dies. So much for Microsoft Fix It.
5) Windows diagnostics reports that it can re-set the IP profile (or something.) I click yes. The re-set goes through. Connectivity is restored. 10 minutes later, connectivity is lost. Just a red X in the tray. No connection of any kind, not even that daft 'Local Connection' only alert.
6) Reboot. Yet again. BT Desktop Help was installed here and ran OK when we were using our Netgear DSG34 router. But since the change to the BT Hub, the BT program has never run at all. So-oo. . . It has been uninstalled. And then re-DL'd and re-installed. And though the installation has been completed, clicking on 'launch' has failed to launch anything. But anyway. An hour ago, in one of the brief periods today when the Internet connection was holding up, I Revo-ed out the earlier install, DL'd BT desktop Help and re-installed it. . . and I'm still at the same stage as always, with a Firefox browser page that's open and completely blank and has been for the past 30 minutes. The URL is:
file:///C:/Program%20Files/BT%20Broadband%20Desktop%20Help/btbb/Start.html
Repeated page re-loading gets nowhere. Malwarebytes PRO is turned OFF to prevent any possibility of blocking and the antivirus is termporaily SUSPENDED. This PC runs on Windows standard firewall but even turning that OFF doesn't get the page to load. Copying the address into Internet Explorer in case there's a Firefox problem merely results in Firefox being opened and the same blank page running there.
7) After all that. . . Connection lost yet again and this time, Windows cannot connect at all. It reports that the "wireless network security key is not correct". I happen to know that it is, because this is maybe the 20th time it has reported this in the past 10 days and every time I have to key in the "correct" key all over again. . . at which point Windows still says it isn't correct and cannot repair.
Turning off the computer completely, unplugging from the wall, holding in the power switch for a full minute to clear the circuits, traipsing up and dowen three flights of stairs to turn off the hub, then wait, then turn the power back onm again. . . Ah, wot fun times I'm having here with my particular versioin of Infinity (as in, an infinity of connectivcity problems.)
Summary: I seem to be being simultaneously hit with one issue after another.
I'm bewildered as to why ever since Infinity was installed here, my upload speed is generally faster than my download speed. I'm not happy with endless Internet connection failures though am thinking that Vista is playing a large part here with its "wrong security key" and unending 'Local Only / Limited Connection' failures. I do miss my Netgear router and the ability to access a fantastic help menu and re-boot directly from the desktop without having to keep going up and down three flights of sdtairs to do so (I haven't been able to find out how toe access the BT Hub remotely.)
Above all though: I'm really tired of repeatedly trying to run freshly downloaded and installed BT Desktop Help software but getting no further than a blank page because the program has stalled.
If anyone has any advice / suggestions, other than to buy a carrier pigeon, that'd be much appreciated.
Thanks.Thanks again to John and gg30340. Here's an update:
1) BT Desktop Help removed completely from this computer. The uninstaller itself mopped up everything, which surprised me. But anyway.
2) Bt Home Hub manager set up and working. Had to input serial number and create new password. All of this sounds fairly easy and would be if one had the device near the desk. But the idiots who built this property shoved the BT master socket inside the garage next to the door. Our two home computers are on the third floor. To ensure the wireless signal strength is OK, the Hub and Infinity module/device/whatever it's called are on a high shelf. It's a major job to even reach the darn things, never mind read the labels seeing as how the BT Infinity engineer was good enough to tidy up the cabling and make a very tight connection to the wall socket.
3) I had hoped to be able to back up the Hub's settings, seeing as the software provides for Advanced Settings / System / Backup. But not on mine (Hub 3.0). All that System allows is choosing which internet clock to define the accurate time. Everything else in System is just a pattern of short lines as if trying to indicate that there's some text there but it's invisible.This is now my second encounter with BT software which, for whatever reason, isn't functioning as it should on this PC.
4) Hub reset to factory fresh, according to BT guide.
5) Reset appears to have achieved nothing apart from requiring the password to be popped in again. After reset, it wasn't even possible to connect to the hub manager. Internet connectivity was eventually established for all of 30 seconds and then, gone.
6) Computer was shut down and then booted anew. Internet connectivity is still. . . dreadful. One minute everything's fine and then, literally,. the next minute a webpage won't load. Even opening the Hub Manager has taken three attempts, i.e., disconnecting from the Internet, re-connecting, failing, and trying twice more until success. Yet all the time these failures are occurring, the tray icon is showing a steady, unwavering green icon for Local and Internet access -- despite the fact, there manifestly isn't any.
7) Speedtest. net tests are actually showing upload and download 'trajectories' going slower and slower and finally halting at some point on the arc, then after a period of up to 30 seconds, suddenly becoming animated again. Speed test results with broadband speed checker UK and Think Broadband's checker are so at variance with one another, and with Speedtest, net, that it seems all three are using different technologies in pursuit of the same thing. Either way, upload speeds continue to be much, much faster than download speeds, a state of affairs I certainly have never encountered before.
8) Speedtest net tests taken in the past 10 minutes, with one test following on from its predecessor, begin at 8.24 down/8.88 up, followed by 5.24 down / 6.40 up, followed by a mind-numbingly lonnnnng 0.62 down / 8.70 up -- in other words, a continuous yo-yoin g of Internet connectivity to the pooint that it actually might as well not even be here (I've had to make five attempts just to get on to this forum. . .)
9) BT Speedtest will necessitate disconnection of everything downstairs and all boxes being lugged up here. This is actually going to require uncoililng tied-off cabling and hanging off a stepladder to do so -- though I surely can't be the only person in Britain who doesn't have a nice, handy BT master socket in their study or lounge. That said though: until we switched to Infinity, we *never* experienced these kinds of horrendous connectivity problems and never had need to unplug the Netgear router downstairs and bring it upstairs to connect directly to tjhe desktop PC so BT's own test could be run.
I'll just have to get to work dismantling stuff tomorrow. However, I have to say that after a factory re-set which has changed nothing at all, I'm beginning to think there's a problem with the BT line itself (hence why I'm happy to follow the advice here, though less than happy at the prospect of the messing about involved.)
Thanks, you two, for your patient help, and also for clarifying the situation re the three signal paths being shown on inSSIDer. At least I know that's usual now! And now, hopefully, when I press 'Post', I won't be faced with an endlessly spinning Firefox circle culminating in what may well be, or seem to be, the 57,938th time today of seeing "Page Not Found". . . -
PHP and MySQL Connection problem
I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
"Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
I know the user, password, etc. work, as I can access the MySQL database with other software.
I checked with my host and they say there are no permission problems on their end.
I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
Any help would be appreciated.I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
Is there some other testing server that I should be aware of?

Hi
I am experiencing wireless connection problem on 4s after ios 8.1 upgrade. The wireless icon appears showing that it's connected but webpages do not load. I have checked my internet connection with other devices and seems to be alright. what to do?
I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
Would you please help me out? I would really appreciate it.Hi..
Restart your router then restart the iPhone to test.

Problem install ovi store and ovi maps?
my phone nokia C7 can not turn on, then I use a three finger salute to hard reset, and my phone can turn on again, but social networking application, ovi store and ovi maps are lost, I tried installing again, but always "unable to install", while applications else could, what happened? what should I do? I want to install it again.
Unfortunately that is one of the outstanding issues with the current firmware in the N8, E7 and C7. The hard reset does not reinstall Qt which is required for the apps you mentions. See this.
/t5/Nseries-and-S60-Smartphones/N8-Maps-problem-after-hard-reset/td-p/783327
Although it is possible to reinstall Qt, the process is highly complicated and should only be atempted by expert users. My suggestion would be to either get your phone reflashed at your local Nokia Care Point or to wait for the next firmware up[date which will hopefully include a fix for this. -
Wireless Connection Problems for Home Hub 3 and Vi...
We have upgraded from BT Home Hub 2 to version 3 and had a BT man (engineer) visit to set it up. He did so with no problems on our PC (wired, runnning XP) and installed all relevant software on the PC and this is connected which so far has been fast (enough - as expected) and reliable. Once the 'main' computer in the house was connected we then tried to connect other things to the internet using this BT Hub 3.
However when attempting to connect our family laptop (running Vista) we hit trouble. Initially I tried to use the icon in the tray (bottom right of the screen) by clicking on connect to a network, then selecting our hub, then inputting the wireless key and going through the menus correctly. It would only connect 'locally' and not recognise the hub. It says identifying then says unidentified (public network BT Hub 3) and only 'local' access which I then change to private network. With my preivious internet I was able to set it up as Home network - now I can only choose between public or private BUT NOT Home, Work or Public.
So I then tried the BT disc that comes with the hub into the laptop. I go through the menus - it asks is the broadband light steady blue? Yes. Click next to continue wireless set up. So I press continue. It then asks for the wireless network/SSID BTHub3- numbers and letters and the wireless key. So I put that in correctly (double checking) and click next. It then says Connecting to your Hub which then gets ticked but then the checking wireless key doesn't tick - it crosses, and says failed. It asks me to check I typed the numbers and letters correctly (I am sure of that) and It goes to Manuel set up. Where I select my hub and again type in the wireless key and click next. But the same thing happens - connecting to your hub gets ticked but checking wireless key fails.
I then get a message that says i should do a wired set up, which I can do and works but on the laptop wired solutions is just not satisfactory - laptops need wireless connectivity. Is this a problem with my laptop, Vista or the hub/modem or a combination.
I also have been able to connect other things to the internet such as a netbook (running Windows 7) and a games console. Please comment if anthing needs explaining or more detail. Your help will be much appreciated. Thank you in advance.
Solved!
Go to Solution.John46: I uninstalled the Hub programmes you said to. I then tried to connect to a network (wirelessly - accessed either by going to Start - Connect to or from the icon in the tray (bottom right). I selected my hub and clicked connect. It does its thing and says 'successfully connected to...' I close that and go onto Network and Sharing Center and it shows its trying to identify the network and wait a few seconds it then shows 'unidentified network (public network)...' and that I have only got local access and so cannot surf the web.
As I mentioned in my earlier post:
With my previous Internet I was able to set it up as Home network - now I can only choose between public or private BUT not got the choice between Home, Work or Public.
Hope I've explained myself. -
Cache and/or Connection problems under load
I have a Kodo web app that's been running just fine in
production for many months now. However, recently the web
traffic has shot up by a huge amount, literally overnight.
But unfortunately, it's caused the app to fail very ungracefully
under the strain.
It's been a crazy few days, and I haven't been able to do
very much analysis because of higher priorities. But from
what I have been able to gleen, it now looks like Kodo is
the most likely culprit. From what I've read in other messages
here, it appears others may have been experiencing similar
problems.
My environment: Redhat Linux 8, Postgres 7.3.4 with the
included JDBC3 driver, Apache 1.3.x, Tomcat 4.1.x and the
webapp connector. Similar behavior was seen with Apache 2.x,
Tomcat 4.1.x and the JK2 connector (that was on the new machine
I setup to handle the new traffic, which, of course, died the
night before).
As I mentioned, this app has been running reliably for
months with no problems. But when placed under heavy load,
it appears to get into some sort of pathological state where
it slows down dramatically (asymptotically?) to the point where
it's effectively locked up. In one case, where the app was
left running for several hours in this state, requests were
taking 90 minutes to complete (normal is 1-5 seconds).
From what I can deduce, there seem to be four things
going on, three of which have been mentioned in recent threads
here:
1) Excessive memory consumption. When the app is
operating normally, I see fairly flat memory usage for
the JVM process. Under load, the JVM steadily expands
until it hits its heap limit. I've gotten OutOfMemory
exceptions with a heap size of 350MB, which should be plenty.
2) Level 2 cache locking issues. I've seen dozens of
threads waiting on a lock in the DataCache code. Not sure
if there's a deadlock happening here or just that the
threads are waiting on a lock that's being held for a long time.
3) Database Connection leaks or contention. I see threads
spinning in the DataSource code trying to get a connection.
I also see dozens of connections from the Postgres side which
seem to be sitting idle, but in the middle of a transaction.
When things get bad, I also see exceptions being thrown because
of timeouts waiting for a connection to become available. It's
a web app, PMs should not be tied up for more than a few seconds.
4) CPU usage pegged or nearly so for the JVM. I suspect
this is related to #3. Something very bad is going on here.
If I stop all inbound requests to the JVM when it's in this
bad state, it will continue to burn CPU at 90%+ for a very
long time. I think it will eventually finish what it's doing,
but I haven't had the luxury of waiting for it. It's definitely
not a linear slowdown proportional to the load.
Attached are my kodo.properties file and some thread stack
traces along with some comments. Any advice would be greatly
appreciated. This is not a complicated app nor am I doing
anything unusual. It doesn't seem logical that Kodo could
breakdown so dramatically under load, so I'm hoping it's some
sort of interaction thing that I can work around.
Thanks.

does not need to read any. As result if you iterate over 100 objects in your
query and for each object resolve reference to another object (always the
same) kodo will request 100 database connections from the pool (and note
they issue rollback on every time they return a connection to the pool so
getting connection might be fairly expensive)
In conjunction with level 2 cache contention this causes application to go
into a stupor.
Try to go back to 2.5.2 (or may be 2.5.4 they promised in the near future
with a workaround) or use "persistent-manager" connection retention if you
discard PM after each HTTP invocation - it will take care of connection
pooling issue. As far as L2 cache I was unable to find any work around so
far - see if you might be better of without cache. You might if your object
graph is not very complex

I have a Kodo web app that's been running just fine in
production for many months now. However, recently the web
traffic has shot up by a huge amount, literally overnight.
But unfortunately, it's caused the app to fail very ungracefully
under the strain.
It's been a crazy few days, and I haven't been able to do
very much analysis because of higher priorities. But from
what I have been able to gleen, it now looks like Kodo is
the most likely culprit. From what I've read in other messages
here, it appears others may have been experiencing similar
problems.
My environment: Redhat Linux 8, Postgres 7.3.4 with the
included JDBC3 driver, Apache 1.3.x, Tomcat 4.1.x and the
webapp connector. Similar behavior was seen with Apache 2.x,
Tomcat 4.1.x and the JK2 connector (that was on the new machine
I setup to handle the new traffic, which, of course, died the
night before).
As I mentioned, this app has been running reliably for
months with no problems. But when placed under heavy load,
it appears to get into some sort of pathological state where
it slows down dramatically (asymptotically?) to the point where
it's effectively locked up. In one case, where the app was
left running for several hours in this state, requests were
taking 90 minutes to complete (normal is 1-5 seconds).
From what I can deduce, there seem to be four things
going on, three of which have been mentioned in recent threads
here:
1) Excessive memory consumption. When the app is
operating normally, I see fairly flat memory usage for
the JVM process. Under load, the JVM steadily expands
until it hits its heap limit. I've gotten OutOfMemory
exceptions with a heap size of 350MB, which should be plenty.
2) Level 2 cache locking issues. I've seen dozens of
threads waiting on a lock in the DataCache code. Not sure
if there's a deadlock happening here or just that the
threads are waiting on a lock that's being held for a long time.
3) Database Connection leaks or contention. I see threads
spinning in the DataSource code trying to get a connection.
I also see dozens of connections from the Postgres side which
seem to be sitting idle, but in the middle of a transaction.
When things get bad, I also see exceptions being thrown because
of timeouts waiting for a connection to become available. It's
a web app, PMs should not be tied up for more than a few seconds.
4) CPU usage pegged or nearly so for the JVM. I suspect
this is related to #3. Something very bad is going on here.
If I stop all inbound requests to the JVM when it's in this
bad state, it will continue to burn CPU at 90%+ for a very
long time. I think it will eventually finish what it's doing,
but I haven't had the luxury of waiting for it. It's definitely
not a linear slowdown proportional to the load.
Attached are my kodo.properties file and some thread stack
traces along with some comments. Any advice would be greatly
appreciated. This is not a complicated app nor am I doing
anything unusual. It doesn't seem logical that Kodo could
breakdown so dramatically under load, so I'm hoping it's some
sort of interaction thing that I can work around.
Thanks.

With cahce enabled, 2.5.3
Here the app had recently slowed down and then effectively locked up.
There where many outstanding web requests that were not receiving output.
At this point most threads seemed to be waiting at the same location.
There were a large number of active database connections and most of
them had open transactions (according to pg_stat_activity). The app
was not responding to any web requests.
It would seem that db transactions had been started, then the thread
got stuck for a long time on a synchronization lock in the cache lookup.
Below are two randomly chosen thread stack dumps.

while running slow, 2.5.3
At this point, the app had been running several hours normally, then
apparently slowed down and locked up while I was away. When looking
at the app threads and database activity, everything appeared idle.
No transactions seemed to be open in the db. But the app was not
behaving normally. Web requests that did not make use of JDO worked
fine (but slow). But requests that hit the db either blocked or were
very slow to respond.
Looking back at the log, there had been a large number of requests
that threw exceptions because they could not get a connection within
five seconds.
Most threads were idle, waiting on read, but some were in the state
shown by the following two stack dumps. Unlike the cache threads above,
they did not seem to be waiting for a lock to be granted, they seemed
to be spinning in the connection management code. Apparently trying
to get a connection. I suspended and resumed the same thread repeatedly
and it always seemd to be doing the same thing. Single stepping was
very difficult because the debugger was slow to respond, apparently
because of other threads also busy spinning.
Postgres indicated that there where lots of connections open and
that they were all idle, so there should not have been a shortage
of connections in the pool. There are two mysteries here: 1) why
can't this thread get a connection? and 2) Why is it busy spinning?

With cache disabled 2.4.3
This run was an accident. I inadvertently ran the app with the older
2.4.3 version of Kodo, with the cache disabled. This one got into trouble
almost immediately. It also seemed to lockup with lots of opentransactions
in the db. It's also interesting that these two threads also seem to be
hanging around the same method as in 2.5.3.

Who can shed some light on my ongoing connection problem.
After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,
Regards form Curacao, Dutch Caribean.
